Compact 12 Vdc delay/timer for fail-safe locks. The CDVI VHLD holds the lock output off when power is re-applied for an adjustable delay (3–10 seconds), then restores power. Ideal for simple push-button RTE operation, it provides a space-saving solution without an additional relay or timer.

• Adjustable delay: 3–10 seconds for short hold-off timing.
• Supply: 10–15 Vdc (nominal 12 Vdc).
• Single relay output (1 x NO/NC) suitable for typical lock currents — consult datasheet for exact ratings.
• Compact module for PCB or enclosure mounting (approx. 65 × 24 × 16 mm).
• IP22 rated; intended for fail-safe locking devices.

Who it’s for: Installers and integrators needing a simple, reliable hold-off for fail-safe locks in access control systems. Works well in both small commercial and residential installations where a short configurable delay is required.

Safety & compliance: Refer to the CDVI VHLD datasheet and installation manual for full electrical ratings, installation instructions and any applicable markings (CE / UKCA). If your locking device approaches the module’s contact rating, use an appropriately sized protection relay to avoid overloading the VHLD.
